GEAR GP-RING 2264352 - Caterpillar

Table 1
Torque Converter Pressure    
Pressure     Pressure Tap     Pressure at High Idle     Adjustment    
Lockup Clutch     (A)     Stabilized pressure with an activated solenoid is
1380 kPa (200 psi) to
1860 kPa (270 psi).
Pressure is less than
170 kPa (25 psi) when the solenoid is not activated.     -    
Torque Converter Inlet P3     (C)     Maximum pressure with cold oil is
930 kPa (135 psi).     -    
Impeller Clutch     (D)     Minimum clutch engagement pressure is
2200 kPa (320 psi).
Maximum clutch pressure is
2550 kPa (370 psi).
Hold pressure is
530 kPa (75 psi) to
830 kPa (120 psi).
Minimum pressure is
140 kPa (20 psi).     -    
Torque Converter Outlet     (G)     Maximum pressure is
550 kPa (80 psi).
Minimum pressure is
415 kPa (60 psi).
(These pressures are for a machine in third speed, with activated brakes, with installed axle shafts, and with the converter in a stall condition.)     Add spacers (16) or remove spacers (16).

The drive shaft rotates between the torque converter and the transmission whenever the engine is running. Contact with the rotating shaft can result in personal injury or death.The rotating shaft is located under the implement and steering pumps. Do not allow personnel into the pump bay area behind the cab when the engine is running.
Personal injury or death can result from sudden machine movement.Sudden movement of the machine can cause injury to persons on or near the machine.To prevent injury or death, make sure that the area around the machine is clear of personnel and obstructions before moving the machine to perform the test that follows.
Note: Make sure that the Left Service Brake Pedal Position Sensor is calibrated correctly before performing pressure tests. The test values can be affected if the Left Service Brake Pedal Position Sensor is not calibrated correctly.Reference: Refer to Service Manual, SENR5704, "Electronic Transmission Control System" for the calibration procedure for the Left Service Brake Pedal Position Sensor.Note: The 990 Wheel Loader and 844 Wheel Tractor are NOT equipped with the reduced/maximum rimpull feature.
Install a hose and a 4130 kPa (600 psi) pressure gauge on pressure tap (D) .
Engage the parking brake and place the transmission in neutral. Start the engine.
Move the reduced/maximum rimpull switch (if equipped) to the MAXIMUM position.
